Kathy Andrews - Coming onto mom

She grinned up at him, "You can feel me up, Billy. I'm going to do something for you that will make you very, very happy."

Billy's hand moved into her smock, his eyes watching her with a hot glow. He ran his hands through the thick hair of Doctor Nancy's cunt.

"Feel where you want, honey," she purred, nuzzling the seeping head of his cock against her cheek. "Feel me all over, if you want to. Feel my cunt, feel my legs, feel my tits, feel my ass."

She opened her mouth, and Billy grunted as she closed her lips about his cock. Her mouth was hot and wet, feeling much better than her fist. He choked with pleasure as Doctor Nancy lowered her mouth until she had every inch of his throbbing hard cock in it. His hand moved about the hair of her cunt, past her hip, feeling a swelling cheek of her ass.

Doctor Nancy whimpered with hungry pleasure as she began sucking up and down his cock. She thrilled to the taste of his cock. The young hardness in her mouth was what she wanted, why she loved boys of Billy's age best of all. Men, grown men, had been too rough with her, and she wanted gentleness, wanted to do what she wanted with a cock and balls, not what the man wanted. She loved to teach young boys about fucking and sucking and touching.

She curled her fingers about his balls as her lips glided up and down, her tongue licking. She shivered when the head of his prick brushed the back of her throat. She was anticipating the gush of his sweet come juice into her mouth. It had been some time since she had sucked a young cock off, and with Billy, she knew she had a willing boy.

His hands moved about her body eagerly, as if he couldn't make up his mind where or what to feel. She trembled as his cock throbbed in her mouth. He was dripping a lot, and as her mouth filled, she swallowed the juices thirstily. His hand moved feverishly about her ass, her hip, through the hair of her cunt. The way he moaned excited her, letting her know he was enjoying this. She had no doubt no one else had ever sucked his cock. He had never fucked a girl, but she was sure he jacked off quite a bit. Being the first with a young boy always thrilled her.

Billy began to squirm his ass about. He was no longer feeling of her, but gripping her hip.

"It's all right," she said, sucking from his cock and pressing it at her cheek. "If you have to come, do it, Billy. It's okay if you come in my mouth."

She shoved his hand to her ass, closing his fingers into a firm asscheek.

"Squeeze it, Billy. Squeeze my ass like that. When you feel you're going to come, let it go. I don't mind… you can come in my mouth."

Billy was already trying to press his cock back into her tight, wet, ever-so-hot mouth. Doctor Nancy gurgled and opened her lips. She swallowed his hard-on all the way, her lips writhing in pleasure at the base. She lifted his balls and pressed them to her cheek, moaning as her throat worked at the head of his sweet cock.

His hand dug harshly into her ass cheek. Doctor Nancy wiggled her hips, and began to suck up and down his cock in a frenzy. She was starving to have him come off in her mouth, desperate to feel and taste the steamy spurts of his come juice.

Billy couldn't keep his hips still. He began to pump them up and down. He fucked into Doctor Nancy's sucking mouth, making her whimper with ecstasy. His movements were further evidence of his enjoyment, and she knew she had chosen the right boy this time. She began to suck eagerly, wantonly. She kept her lips tight as they gilded up and down his cock, her tongue in constant motion. He fucked the swollen head of his cock into her throat, and each time he did so, Doctor Nancy's cunt would clench with passion. She was going to come, she knew. She always came when a young cock spurted that deliciously thick come juice into her mouth. She loved the creamy taste of come juice, the sweetness of it as it burned down her throat.

She shoved her free hand beneath his pumping little ass, gripping his ass hard, still clinging to his balls. She made whimpering sounds of ecstasy as she sucked as fast and hard as she could.

"Doctor Nancy!" Billy groaned. "I'm gonna come! Ohhh, I'm really gonna come!"

"Mmmm," she moaned, sucking greedily. Her cunt was boiling now. She twisted her ass into his gripping band.

She mewled when she felt his cock swell inside her mouth. The jism splashed across her tongue hotly. She gave a muffled squeal, swallowing hungrily, her lips pulling. She clamped her hot lips about the head of his cock, licking swiftly about his come-spewing piss hole, tasting the sweetness as his come juice came up out of his tight balls and splashed time and again into her mouth. She held his cock in her mouth until he finished, draining his come juice completely.

"That was a real load, honey," she grinned up at him. "I love a big, hot load of come juice like that."

She buttoned her smock, telling him he could get dressed. She finished up on his chart as he pulled his clothes on.

"Now, not a word, honey," she warned him again. "You do what I asked. Peek at your mother and tell me what she does – and I'll suck you off again."

Billy, dressed now, asked in a trembling voice: "Doctor Nancy, can I fuck you, too?"

Doctor Nancy laughed, puffing him between her legs and hugging him tightly. "Of course you can, darling. You're very sweet to ask." She looked up into his face, her hands cupping his ass. "Next time you can fuck me, okay?"

"Oh, yeah!"

Doctor Nancy informed Joan she wanted to see Billy a week later, assuring her nothing was wrong with him. "In fact, he's about the healthiest boy I've seen."

Neither Billy nor Joan saw the wink that passed between Doctor Nancy and the pretty receptionist. Joan had looked a little guilty, and couldn't bring herself to look into the doctor's face.

In the car on the way home, Joan was aware that her son stared at her openly. It had been some time since she had been looked at just that way. Thinking it was because of what she and the receptionist had done, Joan found it thrilling for her son to stare at her. Not at her really, but at her straining tits. She was puzzled because Billy had never shown an interest in tits or anything else.

Despite the powerful orgasm she had experienced with the pretty girl, Joan found herself reacting to the way Billy looked at her. Her nipples swelled and strained, and her cunt began to pulsate inside her tight jeans. Her reaction was surprising, yet it wasn't. She always responded when a tan looked at her the way her son was. Responded, yes, but she never allowed a man to know her reactions.

Feeling ashamed of herself, she glanced at the front of her son's pants. A faint flush of shame covered her face, and she quickly tuned back to the road. Her son had seen the pretty girl, looked up her dress, and he had gotten extremely horny, his cock pressing at his pants. He had not been ashamed of looking, either. Maybe it was his youth, but maybe it was a growing interest in girls. If it was interest in girls, or what they had under their dresses… Joan shivered as if chilled. But she wasn't chilled; it was a hot, anticipatory thrill.

They arrived home, and not speaking to each other and entered the house. Joan wanted to get out of her tight jeans. The crotch was pulled against her cunt, and normally she would enjoy the pressure. But her cunt had been sucked by the pretty receptionist and the tingles remained.

Billy watched his mother moving down the hall, his eyes on her ass. The jeans outlined his mother's ass very well, and the shape excited him. Remembering what Doctor Nancy had asked him to do, he followed his mother. He innocently stood in her doorway, watching her. Joan had not looked back, never dreaming her son would follow her.

Standing at the side of her bed, she removed her blouse, then slipped her tight jeans down, wiggling her ass. Watching his mother wiggling, seeing the creamy roundness of her ass, Billy felt his cock grow hard.
